    Monodisperse magnetic nanoparticles: Preparation and dispersion in water and oils

    Nanometric maghemite and cobalt ferrite particles are chemically synthesized. The process produces particles polydisperse in size. The positive charges of their surface allow one to disperse them in aqueous ac...

    Synthesis and room temperature magnetic and magneto-optical characterization of size-controlled nickel nanoferrite based ferrofluids

    Nickel ferrite nanoparticles are synthesized bottom up and then peptized in aqueous media resulting in stable magnetic fluids. X-ray powder diffraction and transmission electronic microscopy permit the investi...

    Optimisation and Simulation of an Alternative nano-flash Memory: the SASEM device

    Process simulation are performed in order to simulate the full fabrication process of an alternative nano-flash memory in order to optimise it and to improve the understanding of the dot storage formation. The...

    Confined and Guided Vapor–Liquid–Solid Catalytic Growth of Silicon Nanoribbons: From Nanowires to Structured Silicon-on-Insulator Layers

    The stacking of crystal semiconductor thin films alternated with dielectric layers continuously arouses a sustained interest for its utility in three-dimensional (3D) integration of metal-oxide-semiconductor f...

    Bilayer properties of giant magnetic liposomes formed by cationic pyridine amphiphile and probed by active deformation under magnetic forces

    We synthesize giant magnetic liposomes by a reverse-phase evaporation method (REV) using a new self-assembling Cationic Pyridine Amphiphile (CPA) derived from 1,4-dihydropyridine as liposome-forming agent and ...

    Inversion of thermodiffusive properties of ionic colloidal dispersions in water-DMSO mixtures probed by forced Rayleigh scattering

    Thermodiffusion properties at room temperature of colloidal dispersions of hydroxyl-coated nanoparticles (NPs) are probed in water, in dimethyl sulfoxide (DMSO) and in mixtures of water and DMSO at various pro...
